Tiled Conservatory Roof: Pros, Cost & Options 2026
A tiled conservatory roof replaces the glazed roof with an insulated, lightweight solid roof — making the room warm in winter, cool in summer and quiet in the rain. It is the most popular conservatory upgrade in the UK. Here is what it costs, how it is built, and when it beats a glass roof.
What is a tiled conservatory roof?
A tiled conservatory roof is a lightweight, insulated warm-roof system that replaces the original glass or polycarbonate roof. Insulated rafters and boards go over the existing frame, finished with lightweight tiles or slate outside and a plastered, insulated ceiling inside. One or two rooflights are usually added to keep the room bright.
Tiled conservatory roof cost 2026
A tiled conservatory roof typically costs £6,000–£12,000 in 2026 for a standard lean-to or Victorian conservatory, including the internal plastered ceiling. Larger or gable-fronted conservatories, premium slate finishes and extra rooflights push the figure higher. Frame reinforcement, if needed, adds to the total.
Pros and cons vs a glass roof
Pros: far better insulation, no summer overheating or winter chill, much quieter in rain, and a true year-round room. Cons: less natural light than glass (offset with rooflights), it adds weight so the frames must be checked, and it usually needs Building Control sign-off. A glass roof keeps more light but never matches a tiled roof for warmth and quiet.
How to choose and compare quotes
1. Confirm the frames can take it
A tiled roof is heavier than glass, so the installer must verify the existing frames and base can carry it, or price reinforcement.
2. Choose tile or slate finish
Lightweight tiles are cheaper; slate looks sharper but costs more. Match the finish to your house roof where you can.
3. Plan rooflights for daylight
Add one or more rooflights so the room stays bright — agree their number and position before work starts.
4. Get three like-for-like quotes
Compare on the same roof system, finish, rooflights and internal ceiling so you judge quality, not just price.
